In this crash file, it was a drag and drop issue involved with the UI of a plug in. You had these in memory:
FabFilter Pro-Q 4 4.02, Pro-R 2 2.04, Pro-L 2 2.24, Saturn 2 2.11
u-he Presswerk 1.1.6
Spectrasonics Omnisphere 2.8.7c, Keyscape 1.5.2c
Xfer Serum2 2.0.20
Native Instruments Kontakt 8.5.0
Wavesfactory Spectre 1.5.6
dSONIQ Realphones 2.2.0
Three-Body SpecCraft 1.4.1
While you can say “Cubase is buggy,” and on your system you may be right, to actually solve the issue you’d have to do some explicit testing with each different plugin, one at a time. Or just pay explicit attention and identify which plugin you were working on. I’m not saying it’s NOT a Cubase component, but to arrive at that conclusion you’d need to test very thoroughly.
Just my opinion.
